SOME THOUGHTS ON AUTOMATION IN PHOTOGRAMMETRY,
Abstract
The efforts to make photogrammetric mapping automatic have produced many ingenious devices but, as a whole, have resulted in only a limited improvement in the 'output per dollar' figure. An examination of various existing and proposed solutions shows that the most serious obstacle to the development of economically justifiable automatic mapping systems is the relatively slow speed at which the sensor systems of the automatic plotter can scan the photographs while maintaining an adequate accuracy level. Use of a flying spot scanner with a monitoring system is proposed as one possible solution to the problem of fast and accurate scanning. (Author)
